The concentration of the four PFAS (PFAS4) considered to be the most dangerous for health exceeds the standard of 4 nanograms per litre of water for a significant part of the water consumed in Brussels, La Dernière Heure reports.
Alain Maron, Brussels’ Minister of the Environment, on Wednesday said that the 20 PFAS detected by Vivaqua since 2020 are within the limit of 100 nanograms per litre of water, the standards which will also come into force in Brussels next year.
The proposed Brussels regional alarm threshold of 30 nanograms per litre is also not exceeded.
However, regional deputy Christophe De Beukelaer has uncovered information regarding the four most dangerous PFAS from Vivaqua. The PFAS4 rate detected in the Rhode reservoir significantly exceeds the Danish standard (2 ng/l) and Flemish indicative threshold (4 ng/l).
Between October 2021 and October of this year, average PFAS4 concentration in this reservoir, supplying over half of Brussels’ taps, reached 6.9 ng/l.
Callois and Uccle reservoirs, serving the capital’s other half, also have concentrations higher than Danish standards but less than the Flemish threshold.
